California bungalow is an alternative name for the American Craftsman style of residential architecture, when it was applied to small-to-medium-sized homes rather than the large "ultimate bungalow" houses of designers like Greene and Greene. California bungalows became popular in suburban neighborhoods across the United States, and to varying extents elsewhere, from around 1910 to 1939.

American Craftsman is an American domestic architectural style, inspired by the Arts and Crafts movement, which included interior design, landscape design, applied arts, and decorative arts, beginning in the last years of the 19th century. Its immediate ancestors in American architecture are the Shingle style, which began the move away from Victorian ornamentation toward simpler forms, and the Prairie style of Frank Lloyd Wright.
